Have you tried drawing a graph of each of them?

There is not going to be any "formula" for the solution, you will have to use some kind of numeric solution. The simplest is Office Shredder's suggestion- accurately graph y= tan x and y= x and measure the x coordinate where the graphs cross.

Are my answer is correct?
